Chicago Building code Violations

[Franklin Azie]

Hey guys, I am looking to purchase my first building in Chicago and I have a couple of questions about how the violations work.

I looked up the building and it seemed to me like there were some violations. I told the owner this and he told me that there are no violations and that the city inspected the property but I want to be absolutely sure. Please see below what I found when looking up the building.

12743222	05/03/2019	CLOSED	DEMO COURT
12697734	01/09/2019	CLOSED	DEMO COURT
12343668	10/11/2018	CLOSED	DEMO COURT
12313591	08/22/2017	CLOSED	CHECKLIST INSPECTION
11690691	10/30/2015	CLOSED	CHECKLIST INSPECTION
11419342	01/13/2015	FAILED	PLUMBING COMPLAINT INSPECTION
11361163	11/14/2014	FAILED	CONSERVATION COMPLAINT INSPECT
11361113	11/12/2014	FAILED	CONSERVATION COMPLAINT INSPECT

I see that the building was in Demo court but those were closed. In 2015 and 2014 the building failed for a plumbing complaint inspection and conservation complaint inspections. My question is this: If he in fact took care of this would the status change from FAILED to CLOSED? Or does the FAILED Designation stay there?

How am I suppose to know or where do I need to go to see whether a previous violation was taken care of and no longer against the building?
